Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. No power ventilation system on the roof of the plant, can achieve very good ventilation effect. Because often due to the operation of machine tools to produce heat and smoke pollution within the plant, according to the "thermal expansion and contraction," the principle of hot air expands, so the number of molecules in a given volume of air is reduced, relative density of hot air cooler air will be small , that hot air lighter than cold air, so the indoor hot air to rise roof exhaust fan manufacturers, cold air to drop, heat or indoor smoke pollution will gather near the roof, so the indoor temperature high pressure. Then as long as the rotation of the turbine on the roof with no power fan, indoor heat or smoke pollution will be void by the blades to spin works out outdoor diversion method, when the heat is withdrawn without power ventilators interior will produce low pressure, The outdoor air is lower than the high pressure, the air flows into the interior roof exhaust fan quotes, fill the space heat is extracted, and then to adjust the temperature, to the decontamination of smoke effects, clean indoor air becomes cool. Factory explosion-proof axial fans, Sidewall Exhaust machine, HTF exhaust fan, Francis fan, EX explosion-proof axial fan, multi-leaf dampers, roof fans, valves, smoke damper, no power ventilators, exhaust fans fiberglass roof exhaust fans, ventilation fans, fiberglass products, fiberglass products, CDZ ultra low noise axial fans, Grille, coal mine explosion-proof axial fan with elbow fans, explosion-proof fans, FT35-11 FRP axial fan roof exhaust fan, single Grille, HL3-2A Francis fan, DZ low noise axial fan ventilation equipment Liaocheng Flextronics Ltd. specializes in non-powered fans and non-powered natural ventilation, etc. No power ventilation function: 1, automatic extraction plants, heat and moisture, dust, odors, smoke, odor, chemical raw materials, such as housing, the air fresh, comfortable. 2, reduce indoor, warehouses, workshops or factories inside temperature of 2-3 degrees to avoid the summer heat stress and irritable mood, reduce the impact of high temperature on the storage of products or raw materials. 3, according to natural climate ventilators automatic operation, no power, saving energy and money. Family residential one-time investment of several decades Bai yuan can enjoy the comfort, factories, warehouses investment installation can save a lot of power consumption, and the effect is significant roof exhaust fan manufacturers | Flextronics ventilators (certified) | Ningxia roof row Smoke from Liaocheng Flextronics fan ventilation equipment Limited.
